Modifying Location Data During Active Wireless Sessions

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing positioning protocols, such as LPP and LPPe, do not allow for the modification of location-related data or trigger conditions during an ongoing data transfer session, leading to delays and resource inefficiencies, as they require aborting and restarting the transfer, which can result in loss of data and increased processing and signaling resources.

Innovation Solution

The introduction of additional control procedures allows for the modification of assistance data or location information transfer without aborting the session, enabling dynamic changes to the type and periodicity of data transfer, ensuring resource efficiency and data integrity by maintaining compatibility with existing LPP procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the location server aborts and restarts the data transfer session to modify location-related data, then the modification can be applied, but data loss occurs and processing resources are increased

Engineering Contradiction:

Improveability to modify data transferVSAvoidlocation data loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent applies dynamics by enabling the data transfer session to be modified dynamically during operation. The location server can change data transfer parameters (type, periodicity, trigger conditions) without aborting the session, allowing the system to adapt to changing requirements while maintaining continuous data flow and avoiding data loss.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by establishing a control procedure before modifying data transfer parameters. The location server sends a control message to the mobile device specifying the intended modifications, allowing the device to prepare for and smoothly transition to the new parameters without interrupting the data transfer session.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the location server aborts and restarts the data transfer session to modify location-related data, then the modification can be applied, but processing resources and signaling resources are increased

Engineering Contradiction:

Improveability to modify data transferVSAvoidprocessing and signaling resources

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies continuity of useful action by maintaining the data transfer session active during modifications. Instead of aborting and restarting, the system continues transferring data while incorporating modified parameters through control messages, thereby avoiding the resource consumption associated with session termination and re-establishment.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent segments the data transfer process into two independent parts: a control channel for modifying parameters and a data channel for transferring location-related data. This segmentation allows modifications to be applied without interrupting the data transfer, reducing the need for resource-intensive session aborts and restarts.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the location server uses existing LPP procedures for data transfer, then protocol compatibility is maintained, but the ability to modify ongoing transfers is limited

Engineering Contradiction:

Improveprotocol compatibilityVSAvoidability to modify data transfer

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a control procedure that works within the existing LPP framework while adding modification capability. The control message can be sent during ongoing data transfer sessions and is processed by both the location server and mobile device, enabling modifications without requiring a completely new protocol, thus maintaining compatibility while enhancing adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
